Choosing a CPU air cooler: towers, low-profile and what the numbers mean
How to choose a CPU air cooler: towers, top-down and low-profile designs, heat pipes, fins and fans, noise figures, socket mounts, clearance and when an AIO fits.
Delidded: CPU mods, cooling and old PCs that still earn their keep
The LGA 771 to 775 Xeon mod
Run a 45 nm Xeon in a Core 2 board: what the adapter sticker does, which chipsets cope, and how to get through the BIOS side. Five pages, in order:
Latest builds
CPU coolers that still fit LGA 775
LGA 775 uses 72 mm hole spacing, not the 75 mm of later Intel sockets. How to read socket lists, push pins versus backplates, and height and RAM clearance.
Best thermal paste for a CPU: how to choose, and four sensible picks
The best thermal paste for a CPU is non-conductive, needs no curing and comes in a sensible tube. How to read specs, four picks by use and a liquid metal warning.
Thermal pad vs thermal paste: which one each part of your PC needs
Thermal pad vs thermal paste: paste goes on CPU and GPU dies, pads fill measured gaps over VRAM, VRMs and M.2 drives. How to pick thickness, plus three picks.
Cleaning thermal paste with isopropyl alcohol, step by step
Isopropyl alcohol for cleaning thermal paste: why 90 to 99 percent, which wipes, the CPU lid and cooler base, paste in the socket, liquid metal and drying time.
Cleaning dust out of an old PC without breaking anything
Clear dust from an old desktop safely: power and static first, fans held still, heatsinks and PSU vents blown out, no vacuum inside, and what to inspect.
BIOS, microcode and CPU lists
LGA 771 Xeon microcode
Why a desktop BIOS may not know your Xeon, and what to add.
Microcode in an AMI BIOS
Patching an AMIBIOS 8 image and flashing it back safely.
